Are you celebrating it? I AM! I have to, actually.
They only asked you to switch off the lights. Yeah, this means you can still turn the TV on. LOL
Let's help them to reach 1 billion people. Join them at 8.30-9.30pm on the 28th of March 2009 and do switch off most of the electrical appliances in your house. Go out of the house to see if it is really working! Join your friends to celebrate this historical event. Heh. =]
